This series of valves is divided into three driving modes: manual, pneumatic, and electric. It has the advantages of smooth operation, small size, reliable use, good sealing performance, and long service life, and can be widely used in ultra-high vacuum equipment. The valve is powered by manually rotating the handle, compressed air pushing the cylinder, and motor transmission torque. The connecting rod mechanism is pushed (pulled) by the transmission rod, and the driving body moves along the axial direction. The driving body is connected to the valve plate through a swing rod or steel ball to complete the opening and closing actions of the valve plate. The working medium of the valve is air and non corrosive gases.
Characteristic:
1.There are two types of shaft seals to choose from: bellows seal and fluororubber seal. The other seals are fluororubber and designed without lubricants;
2.The valve body is welded internally with stainless steel, resulting in a low leakage rate;
3.The valve body adopts a reinforced rib structure, with small volume, light weight, and beautiful appearance;
4.Adopting a dual guide bearing roller mechanism, the movement is smooth; The valve plate has an integral structure with uniform support.
